Tried with:
GCC with gcj, precompiled with binutils 2.15.94:

http://www.thisiscool.net/gcc40-20050324.tar.bz2
Also tried with a self compiled gcc 4.0 and with binutils head (july 1st 2005).
Most applications I compile and link produce working executables. This is true
at -O0 and -O1 with gcc.
Specific larger applications compile and link, but when compiled -O1 and above,
the resulting .exe is reported to not be a valid win32 application. Win32
reports:
app.exe is not a valid Win32 application.
Looking in the .exe (view it in hex), the .rdata section has more than /1500
entries. I don't know what they are, but when the number exceeds approx /1500,
the apps are no longer valid. (just an observation)
Attached is a simple big.java file. Compiles and links fine. The
resulting .exe works fine at -O0, but not -O1 and above on win32. The
resulting binary works fine on linux at any optimization level.
gcj -O1 --main=big big.java -o big
big.exe is not a valid Win32 Application
It is just a bunch of strings of increasing length. This seems to fill
up the .rdata section. With less than 150 strings the .exe works. At -O0 it
works. More than 175 strings and -O1 or above and the .exe becomes invalid.
I don't know what else to try, but it seems to be a binutils (as or ld) bug
(gcc bugmaster suggests the same).
